Overhaul the RequestFactory server code.
Make RequestFactory usable from non-GWT code.
http://code.google.com/p/google-web-toolkit/wiki/RequestFactory_2_1_1
Move AutoBeans to a top-level package and add AutoBeanCodex.
Add explicit support for Collections and Maps to AutoBeanVisitor.
Add support to AutoBean and AutoBeanCodex for Map properties.
Add @PropertyName annotation to decrease the size of the RF payload.
